NEEDLE-HOLDER non TALKING-MACHINES Specification of Letters Patent.

Application filed March 20, 1908.

Patented April 13, 1909.

Serial No. 422,227.

To all whom it may concern:

Be it known that I, WILBUR B. CLAFLIN, a

, citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented new and useful Improvements-in Needle-Holders for Talking-Machines; and I do declare'the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which 111 a socket in a bracket carried by the sound box by means of a set screw, which screw is carried by the bracket and, tightened against the needle shank.

While the use of a thorn-or wooden needle is well known, it has been found difficult to carry such needles in a manner to securethe best results therefrom, owing to the fact that when attached to the sound box in the usual manner, the lpith in the portion of the thorn the set screw impinges, allows the thorn shell to give inwardly when pressed by the set screw,'thereby causing the needle to loosen and mar the tone of the machine.

It is the object of my invention to provide a device for holding such needles so as to obviate the loosenin noted and thereby secure a full rich tone t erefrom, and in accom plishing this I have provided the improved details of structure which will presently be more fully described and pointed out in the claims, reference being had'to the accompanying drawings, in which 2- Figure I is a perspective view of an ordinary sound box equipped with a needle and needle holder constructed according to my invention. Fig'. II is an enlarged detail view of a ortion of the needle bracket, together wit the needle holder and point, showing the relative position of the different parts. Fig. III is a view of the needle holder showing the manner of inserting the thorn oint.

Fig. IV is a top plan view of the older.

Fig. Vis a transverse sectional view of the holder bracket on theline VV, Fig. II.

1 Referring more in detail to the parts:

!' l designates a sound box and 2 a needle i bracket which may be of any ordinary and l well known construction, the latter being proi vided with a socket 3 and a set screw4 by means of which a needle or needle holder may be rigidly held in position.

5 designates a point holder having an oilsetsocket member 6 and a shank 7 which latter is adapted to fit within the socket 3 of bracket 2. Extending through member 6 is a socket 8 which'is preferably of a cone shape and projected at a slight inward angle as indicated in Figs. II, III, and IV'.

9 designates the tapering needle point which is adapted to fit within socket 8 with small end of the socket in position for problunt end preferabl in the plane of the top of member 6, so tlat when the holder 18 deposited in the bracket, the upper end of the oint may bear against the lower end of the racket and be held firmly in place to obviate loosening when the machine is in operation. y

While the needle may be cut to the proper length to 'fit the holder, as described, the best results are obtained when athorn or needle of greater length is used, when the point of the thorn is inserted into the socket 8 and the enlarged end broken off, .asindicated in Fig. III, in this way securing a close, tight fit of the point within its. socket and .insuring an engagement of the upper end 0tv the point against the bracket member.

In using my device the sound box and needle bracket are arranged and operated in the manner usual with any well known type insert a needlethe holder member 5 is re- -moved from the bracket and a thorn proupper end of the thorn is broken off asindicated in Fig. III. The holder shank is then inserted into the bracket socket with the upper face of the socket member 6 engaging the lower end of the bracket, and the set screw 3 is tightened against theholder shank to hold the parts in position. The eedle is then placed in the record groove in the usual way and the machine operated, the point be-- ,ingheld against displacement by its engagement with the lower end of the bracket although the close fit of the point within the its'sharpened portion projecting through the jection into the record grooves andwith its of talking machine. When it is desired to jected into and through the socket 8 and pressed until a tight fit is secured, when theholder socket is ordinarily snfiicient to prevent displacement.

After the record is T played and a new needle is desired, the holder is removed'from the bracket after loosening'the metal-screw and the needle point removed from the holder by ressing the rejecting oint against a harllsubstance, a new. oin-tiiiserted and the holder replaced in the racket.

Having thus describedfmy invention what I claim as new therein and desire to secure by Letters Patent is 1*. In a needle for talking machines, a oint 'ihold'er having a shank member, and a aterally projecting socket; member having a downwardly and inwardly projecting socket,

substantial as set forth.

-Ina needle holder for talking machines a holder shank provided with a-laterally proj ecting socket member having a socket tapering longitudinally and toward the shank body, said socket member being adapted to 'receive and hold a tapered needle point wholly by the fit of such point therein.

3. A needle holdei' forv talking machines 25 comprising a needle bracket, a point holder having a shank member. adapted for projection into said bracket and a laterally rejecting socket member having a conoida socket extending therethrough and inclined toward St the shank body, said socket member being free from binding parts but said bracket beingi provided with means for anchoring said shank therein, substantially as set forth.

In testimony whereof I affix my signature 35
